dotnet interop: Hello!

I did some performance testing with ADODB interop object creation, and
noticed that interop objects are created much faster on windows applications
than ASP.NET.

I tested it with this function on both platforms:

Private Function CreateObjects() As TimeSpan

Dim rsData As ADODB.Recordset
Dim lPos As Long
Dim dtStart As DateTime = Now

For lPos = 1 To 5000
rsData = New ADODB.Recordset
Next

Return Now - dtStart

End Function


Windows application gives about 1.8 seconds
ASP.NET (on IIS 5.1) application gives about 15.6 seconds

I'm using .NET Framework v2.0.50727

Why is ASP.NET so much slower, and is there anything to do about it?

John,

Did you set AspCompat=true in your ASP.NET page?

Hi!

That switch doesn't seem to have any affect on the performance.
